The first stage of cell respiration is ___ , the breakdown of ___
to form two molecules of ___
. The resulting molecules may pass through several different pathways, depending on the organism in question. In some organisms, such as yeast,___
occurs. In other organisms, aerobic respiration occurs.

Glycolysis porduces
molecules of NADH and
molecules of ATP (net gain).

In an intermediate stage, pyruvic acid is converted into
. This process produces
molecules of NADH (per glucose molecule).

The Krebs cycle takes acetyl CoA and completely oxidizes it to
. In the process,
molecules of ATP are gained. This process also produces
moecules of NADH and
molecules FADH2. (All of these values are per glucose molecule.)

The
is a system of electron carriers embedded into the inner membrane of the mitochondria. The compounds act to accept energy bearing electrons from
and
and transfer them step-by-step to free
, which is reduced by these electrons combining with hydrogen to form
.

Cold case files recently began re-investigating an old murder case. the murder took place in the park; a young man, james, was hit over the head with a brick and killed. police suspected the jealous former boyfriend of james' wife, karen. whoever killed james may have washed their hands in a near-by bird bath as detectives found blood in the bird bath. since the murder took place before dna fingerprinting was available, the suspected killer, ronnie, went free. detectives are now reviewing the blood evidence using dna fingerprinting. based on the dna fingerprints of all possible suspects, who is james' killer?
